La matrice poreuse (21) est en communication fluidique avec la chambre de stockage de liquide (4), et adsorbe le liquide de la chambre de stockage de liquide (4) au moyen de la force capillaire. L'élément chauffant (22) chauffe et atomise le liquide de la matrice poreuse (21). Le noyau d'atomisation (2) est situé entre la chambre de stockage de liquide (4) et la structure tampon pour les fuites (122). La structure tampon pour les fuites (122) vient en butée contre la matrice poreuse (21), et est utilisée pour renvoyer un liquide s'échappant du canal d'échange de gaz (15) vers la matrice poreuse (21).
